Yeah, I talked to Mike and decided to try applying low heat while holding a counter twist, then walked out into cooler air to set it. One aileron immediately split along the trailing edge seam so I put a drop of thin CA on and stopped. There is almost no structure in the aileron. I was pleased though that the warps were pretty much gone but when I checked again a few days later they were back to exactly the same warp. Based on this I don’t think they can be fixed. My guess is they were taken from the mold prematurely by the builder and honestly I’m not surprised, otherwise this plane would be too good to be “true” at this price. Whether it becomes a trimming issue or not is yet to be determined.

I may be making a mountain out of a molehill and it is hard to show but you can see the curve on these two ailerons, one is concave on top and the other on the bottom. The hinges are centered well and the leading edges are true but on both wings and the warps manifest themselves by being unable to match the root and tip to the wing by a mm or two. Basically it will either average out in flight or it won’t. Mike offered to help me out if my attempts to correct the warps ended in disaster but I didn’t want to ruin them and honestly, until it flies I won’t be certain.

Keep up the posts. I’ll check mine tomorrow when it comes. Unfortunate yours are this way. Like you said, flying will be the decider.

I need help with my T-Can. Do I have to drill holes in the T-Can to make the washers sit flush? Right now they on top and all the pictures that are displayed show they are flush. This is my first build of a pattern plane. Thx for any suggestions.

Default It’s here

OK. It has arrived. Packed very well! Initial fits are all good. Nice touch with the foam on the root ribs on the stab and wings. Sorry, no warps noted. The no manual part is a bonus! No lower hatch. Have to locate the manual for the MLG install.



And more packing

More packing

Trial fits

Double boxed

from what I see yes. Mine does not sit flush with the fuselage. This would be the time to correct that. Yes you would have to drill the tcan holes so the shoulders of the washer sit flush.

Default Mini servos?

So I was expecting to see mini servo cutouts in the horizontal stabs. Instead they are full size. Is that what everyone went with?

Nice! Looks great, Tcan fit is known issue, many have installed a ply plate to reduce and accommodate mini servos, I will. There’s a little bit of “building” involved in these but not much.

I used Futaba 9650 on mine, you will have to add some wood to make the mini servos fit.

Futaba BLS173HV for me. I believe they are the same size as the 9650, and dead accurate as well.

Default Canopy sill

So just to be clear. The canopy sill is 0 correct when setting the incidences? Level the sill and set from there.

Default CG?

Is there a consensus on the CG in relation to the aft side of the wing tube? I see so many.

That's where I had mine. This plane is very tolerant to C/G location.

Just set where you like and the plane tracks well.

I set it at 1/4" behind the wing tube. Never was able to fully remove knife edge pull no matter where C/G was set, mixed it out.

Default Landing gear

After a dozen or so flights I will say it’s a must do to reinforce the gear mount areas. I installed a 3/16” bulkhead to the fwd and aft sides. Of course after the fact.......

It be grass. Very short, very flat. Everyone who has seen the construction of this plane knows while it rocks for the value, the major glue joints are only fillet glued. They separated as a whole assembly. So I went through and wiped it down with alcohol and brushed epoxy mixed with micro balloons on everything I could get to.

Default Incidinces.

I wouldn’t mind seeing a few different opinions on incidences for the wing, stab and cannilizer.
